Date acquired: October 26, 2011
Image Mission Elapsed Time (MET): 228110230
Image ID: 933420
Instrument: Wide Angle Camera (WAC) of the Mercury Dual Imaging System (MDIS)
WAC filter: 7 (748 nanometers)
Center Latitude: 34.92°
Center Longitude: 169.9° E
Resolution: 268 meters/pixel
Scale: This image is approximately 280 kilometers (170 miles) across
Incidence Angle: 86.9°
Emission Angle: 8.1°
Phase Angle: 86.9°
Of Interest: The surface in this image is located near the center of the large Caloris basin. The linear troughs radiating from the lower left corner are part of Pantheon Fossae, while numerous other fractures can be seen crisscrossing the basin's floor. MESSENGER's orbital images are revealing a complicated set of tectonic features within Caloris basin, many more than previously mapped.
This image was acquired as part of MDIS's high-resolution stereo base map. The stereo base map is used in combination with the surface morphology base map to create high-resolution stereo views of Mercury's surface, with an average resolution of 250 meters/pixel (0.16 miles/pixel or 820 feet/pixel) or better. During MESSENGER's one-year mission, the surface morphology base map is acquired during the first 176 days, and the second 176 days are used to acquire the complementary stereo base map, which includes the image here.
The MESSENGER spacecraft is the first ever to orbit the planet Mercury, and the spacecraft's seven scientific instruments and radio science investigation are unraveling the history and evolution of the Solar System's innermost planet.

During the one-year primary mission, MDIS is scheduled to acquire more than 75,000 images in support of MESSENGER's science goals.
